[Repeater-Builder] Mastr II Rx Freq Drift

[Jamey Wright]

I recently rebuilt my 440 repeater and got away from the Mastr II mobile w/ tripler PA and went to a Mastr II Station.  As a part of the upgrade, I sent a set of 2C icoms to International Crystal and had them recrystaled to my frequency.  It has been on the air since the end of December.  When I first put in on, everything was great.  After about 2 weeks, I couldn’t get into it anymore.  After some experimenting, I found that if I tuned down from 449.325 (rx freq) to 449.310 I could bring it up.  Went back to the site with the service monitor and put it back on frequency.  That was 3 weeks ago.  A few days ago, can’t bring up the repeater.  I tried at 449.320.  Bingo!  There it is.   My question…   Is it normal for a crystal to drift that much over the first month or so?  I don’t remember having this problem before but it’s been a while.  No, the building is not climate controlled but is insulated very well and the temperatures have been pretty mild around here lately.   Thanks   Jamey Wright  Systems Analyst Morgan County EMCD 911 Decatur, Al 256-552-0911   Also KD4SIY 444.325 +   Yahoo!
